본 발명은 전방차륜의 캐스터각조정용 컨트롤아암 장착구조에 관한 것으로, 특히 전방차륜의 스트럿트 상단부에 차체의 길이방향에 대해 상하로 원호운동을 하도록 된 컨트롤아암을 배치하여 주행중 차륜의 상하운동에 따른 캐스터각의 변화를 줄이도록 함으로써 차량의 직진안정성을 확보하면서 조타력에 악영향을 미치지 않도록 된 전방차륜의 캐스터각조정용 컨트롤아암 장착구조에 관한 것이다.The present invention relates to a control arm mounting structure for adjusting the caster angle of the front wheel, and in particular, the control arm is arranged in the upper end of the strut of the front wheel to the circular motion in the vertical direction of the vehicle body in accordance with the vertical movement of the wheel while driving The present invention relates to a control arm mounting structure for adjusting the caster angle of the front wheel which ensures the linear stability of the vehicle and thereby does not adversely affect the steering force by reducing the change of the caster angle.
일반적으로 차량의 전방차륜 현가장치중 제3도에 도시된 바와 같은 맥퍼슨형식(Mcpherson Type)의 구조에서는 주행중에 전방차륜(1)이 노면이나 기타 외부조건에 의해 제4도에 도시된 바와 같이 범프(Bump)또는 리바운드(Rebound) 구간사이로 상하운동하게 되는 바, 이때 로어콘트롤아암(도시안됨)의 볼조인트와 스트럿트(2 ; 현가장치중 쇽업소오버와 이를 둘러싸고 있는 코일스프링을 일체로 칭함)의 상단부를 연결한 직선(A)이 형성하는 캐스터각(Caster Angle)이 최초 셋팅된 값과 다르게 커지거나 줄어들게 되는 변화를 일으키게 된다.In general, in the McPherson Type structure as shown in FIG. 3 of the front wheel suspension system of the vehicle, the front wheel 1 is bumped as shown in FIG. 4 by road surface or other external conditions while driving. (Bump) or rebound (between up and down), the ball joint and the strut of the lower control arm (not shown) (2; the suspension of the suspension system and the coil spring surrounding it) The caster angle formed by the straight line A connecting the upper end of is increased or decreased differently from the initially set value.
그런데 상기와 같이 차량이 주행중에 캐스터각의 변화가 심하게 일어나면, 즉 차량내 화물의 적재상태나 제동시와 같이 차고의 변화가 일어날 경우 차량의 운동특성에 큰 변화를 초래하여 직진에 대한 안정성과 조타력에 직접적인 악영향을 미치게 되는 문제점이 있다.However, if the caster angle changes severely while the vehicle is driving as described above, that is, if the garage is changed, such as when the cargo is loaded or braked, the movement characteristics of the vehicle may be greatly changed, resulting in stability and straightness. There is a problem that has a direct adverse effect on the inertia.
이에 본 발명은 상기와 같은 제반 문제점을 해소하기 위해 발명된 것으로, 현가장치중 스트럿트의 상단부에 차체의 길이방향에 대해 상하로 원호운동을 하도록 된 컨트롤아암을 배치시켜 주행중 전방차륜의 상하운동에 따른 캐스터각의 변화를 최소화 함으로써 직진의 안정성을 부가시킬 수 있도록 된 전방차륜의 캐스터각조정용 컨트롤아암 장착구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above-mentioned problems, the control arm arranged to arc up and down with respect to the longitudinal direction of the vehicle body in the upper end of the strut of the suspension device to the vertical movement of the front wheel during driving It is an object of the present invention to provide a control arm mounting structure for adjusting the caster angle of the front wheel to minimize the change of the caster angle accordingly.
상기와 같은 목적을 달성하기 위한 본 발명은, 차량의 전방차륜 현가장치중 맥퍼슨형식의 현가장치에 있어서, 상기 전방차륜의 조향너클에 결합된 스트럿트 상단부에 차체의 길이방향에 대해 상하로 원호운동하도록 컨트롤아암이 링크결합되어 그 타단이 서스펜션타워부의 내측 후벽에 접합된 구조로 되어 있다.The present invention for achieving the above object, in the McPherson-type suspension of the front wheel suspension of the vehicle, the circular motion of the vehicle body in the longitudinal direction of the strut upper end coupled to the steering knuckle of the front wheel The control arm is linked so that the other end thereof is joined to the inner rear wall of the suspension tower portion.
이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명에 따른 컨트롤아암의 장착상태를 개략적으로 도시한 상태도이고, 제2도는 제1도에서 전방차륜의 범퍼/리바운드시에 변화되는 캐스터각을 도시한 그래프이다.FIG. 1 is a state diagram schematically showing a mounting state of a control arm according to the present invention, and FIG. 2 is a graph showing a caster angle which is changed at the bumper / rebound of the front wheel in FIG.
본 발명은 도면에 도시된 바와 같이, 맥퍼슨형식의 현가장치에 있어서, 전방차륜(1)의 조향너클에 결합된 스트럿트(2) 상단부에 차체의 길이방향에 대해 상하로 원호운동하도록 컨트롤아암(3)이 수평하게 링크결합되어 그 타단이 서스펜션타워부(4)의 내측 후벽에 배치되되, 이 컨트롤아암(3)은 스트럿트(2) 상단의 러버마운팅부(5)와 일체화된 구조로 되어 있다.As shown in the drawing, in the McPherson type suspension device, the control arm is configured to arc up and down with respect to the longitudinal direction of the vehicle body at the upper end of the strut 2 coupled to the steering knuckle of the front wheel 1. 3) is horizontally coupled to the other end is disposed on the inner rear wall of the suspension tower portion 4, the control arm (3) has a structure integrated with the rubber mounting portion (5) of the upper end of the strut (2) have.
따라서 상기와 같이 스트럿트(2) 상단에 차체의 길이방향에 대해 상하운동되도록 일단이 서스펜션타워부(4)에 결합된 컨트롤아암(3)은 제2도에 도시된 바와 같이 차량이 주행중 전방차륜(1)이 상하방향으로 범프 및 리바운드될 때 차륜의 캐스터각의 변화를 줄일 수 있게 된다.Therefore, the control arm 3, one end of which is coupled to the suspension tower portion 4 so as to vertically move in the longitudinal direction of the vehicle body on the upper end of the strut 2, as shown in FIG. When (1) is bumped and rebounded in the vertical direction, it is possible to reduce the change in the caster angle of the wheel.
이상 설명한 바와 같이 본 발명 전방차륜의 캐스터각조정용 컨트롤아암 장착구조에 의하면, 상기 전방차륜(1)과 결합된 스트럿트(2)의 상단에 차체의 길이방향으로 상하 원호운동을 하도록 된 컨트롤아암(3)이 결합됨에 따라 전방차륜(1)의 전후방향으로의 자유도를 크게 하여 주어 주행중 차륜의 캐스터각변위를 줄여 직전주행의 안정성을 부가하면서 원활한 조향조작이 이루어질 수 있도록 해준다.As described above, according to the control arm mounting structure for adjusting the caster angle of the front wheel of the present invention, the control arm is configured to vertically and circularly move in the longitudinal direction of the vehicle body on the upper end of the strut 2 coupled to the front wheel 1 ( 3) is combined to increase the degree of freedom in the front and rear direction of the front wheel (1) to reduce the caster angular displacement of the wheel during driving to add to the stability of the last run while smooth steering operation.
